防渗墙是修建在挡水建筑物和透水地层中的地下墙,用来控制渗流,保证建筑物和地基的渗透稳定,减少渗透流量。防渗墙施工技术是从50年代初开始发展起来的,首先在水电建设中采用较多。近年来,江河防洪标准提高,堤防建设大规模展开,防渗墙以其结构可靠、防渗效果好、能适应各种地层条件、修建深度大、施工速度快等优点得以广泛应用。 Impervious walls are underground walls built into retaining structures and permeable formations to control seepage and to stabilize infiltration of buildings and foundations and to reduce permeate flow. Diaphragm wall construction technology is developed from the early 1950s, first of all more in the construction of hydropower. In recent years, rivers and flood control standards improve, embankment construction on a large scale, anti-seepage wall with its reliable structure, anti-seepage effect is good, able to adapt to various formation conditions, the construction of large depth, construction speed and other advantages are widely used.
